Types of electric height adjustable desk frame explained
a) Single column. one motor, one telescopic leg. Series: 501-7 and 501-19
Primarily there are 2 types of multi-leg standing desk frame
b) single motor with driveshaft(s) taking drive to the other leg(s). Series: 501-11, 501-17, 501-25, 501-27, 501-29, 501-49
c) motors in each leg that are electronically syncronised. Series 501-23.
Type b further explanation
The most significant performance difference is that single motor desk frames do not need to be loaded evenly to acheive their lift capacity, eg.. a 501-11 could have an 80kg electronic micro-scope on one end and nothing on the other and it will lift as if the load were evenly spread.
There is also reasonable argument that a single motor system by virtue of having less parts and by being mechanical is inherently more reliable.
With the Conset driveshaft system it is unheard of for the leg height to become out of sync. The traverse cross beam on a Conset single motor desk houses the driveshaft and is usually a fixed length mounted around halfway down between the two legs. Model 501-49 is the only exception to this whereby a single motor system is used but with an adjustable width traverse cross beam that is mounted on the underside of the table top. This allows for the width of the 501-49 frame to be fixed when assembled at 7 different widths in increments of 10cm from 116cm-176cm.
The traverse also acts as a very strong brace to give solid construction for the whole frame, those models with the traverse mounted lower down are more rigid than the 501-49 system but the plus side for 501-49 is the benefit of open space under the desk leaving more room for mobile storage items etc.
Type c further explanation
In rare cases 'out of sync' can occur with any electronic syncronised leg system including the Conset 501-23. In this system each leg has a motor and then electronics are used to syncronise these to lift at exactly the same speed. A motor fault or failure or an error in the electronics can cause the synconisation to fail.
a,b and c are all exceptionally reliable so If we give extreme examples for multi-leg usage this may help explain further:..
1) If an open symetrical sleek design is a priority ie.. for a large boardroom meeting table 250cm x 100cm then 501-23 would be the first choice ...but if for a standard duty office desk 120cm -200cmx100cm then 501-49 would be ideal.
2) If the frame is for a workbench used day in day out with heavy equipment possibly being placed to one end of the top then 501-11 would be the ideal choice.
3) If the office is likely to have variable top sizes including L shapes but generally speaking will have no exceptionally heavy equipment then 501-17, 501-25, 501-27 and 501-29 all have their niche for specific requirements.

Desks with auto-stop
Conset have 2 series with auto-stop built in, 501-29 and 501-27, this is an extra safety system for if the down button is accidentally held on by a person or gets trapped by, for example the arm of a wheel chair.
The system works in a way that if the desk traps something or someone on the downward stroke it will squeeze with a pressure approximately equal to the weight of the table top and contents that have been placed on the table top but then when that pressure equalizes it will automatically stop, effectively stopping the frame lifting itself off the floor.
